Defects recorded against failed normal tests, 2005–2025, grouped by DVSA inspection section. One test can record multiple defects. "vs all bikes" is how often this model's tests record a defect in the group, as a multiple of the all-bike rate.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the X9 beats 0 of its 4 closest rivals (PIAGGIO PX 200 E, LAMBRETTA GP200, HONDA Forza 300/350).

Rivals share this bike's type and sit within ±30% of its engine capacity, ≥ 5,000 tests. Card colour = better/worse first-time pass rate than the X9.

Pass rate by registration year

how each model-year cohort fares · registration year from first use date

Best year to buy used: 2008 (81.8% pass). Weakest: 2007 (74.8%).

First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.

PIAGGIO X9 FAQ

answers computed from the data above · terms in the glossary

Is the PIAGGIO X9 reliable?

The PIAGGIO X9 is less reliable than average for its class: 77.0% of its 21,703 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #4065 of 5426 models.

What does a X9 fail its MOT on most?

steering and suspension — 26% of all defects recorded against failed X9 tests.

What is the best year of X9 to buy used?

By first-time pass rate, 2008-registered examples do best (81.8%) and 2007 worst (74.8%). Condition and history still trump the year.

How many miles will a X9 last?

The median X9 shows 12,186 miles at test, and examples around 50k miles still pass 72.1% of the time — mileage alone rarely kills one.
